4.6.21 for the compound snips, find the dimension b so that a gripping force P wil produce a cutting force of 9P at 1.5 in along the blade from pin A

Figure P-4-6.19 4-6.19. The frame shown in Fig. P-4-6.19 is supported by smooth surfaces at A, B, D, and E. The radius of the pulley supporting the load W is 2 ft. Find the reactions and the total force transmitted by the axle at C to member BE. Radius, = 2.4 Ans. C= W 4-6.20. Determine the components of the force exerted by the axle of the pulley in Fig. P-4-6.20 upon the member AC and upon member CF. On AC: 0.9W down; on CF: 0.7W down and 0.8W right Ans. 4-6.21. For the compound snips shown in Fig. P-4-6.21, find the dimen- sion b so that a gripping force P will produce a cutting force of 9P at 1.5 in. along the blade from pin A. 12 Figure P-4-6.20 b = 2 in. Ans. Figure P-4-6.21 75 Ib 75 lb Figure P-4-6.22
